Abstract

Abstract : A dilithium porphyrin was synthesized by vapor-deposition of metallic lithium onto solid free-base porphyrin. Abstract : A solvent-free dilithium porphyrin was synthesized by direct reaction of free-base meso -tetraphenylporphyrin with elemental lithium in ultra-high vacuum. The reaction product dilithium tetraphenylporphyrin was studied by temperature-programmed desorption mass spectrometry (TPD-MS) and hard X-ray photoelectron spectroscopy (HAXPES). The solid-state reaction is thermodynamically favored, according to density functional theory (DFT) calculations.
